    Abstract: The invention is an automatic pole-zero adjustment circuit for an ionizing radiation spectroscopy system in which an amplitude histogram circuit (56) is used to obtain an amplitude histogram of an acquired spectrum. The shape of a selected peak from the amplitude histogram is analyzed for peak shaped distortion (142, 146) indicating the existence of undershoot or overshoot. An analog correction signal generated by a pole-zero adjustment network (32) is added to cancel existing undershoot or overshoot, so as to minimize distortion of the peak shape. In an alternate embodiment, the correction signal is a digital transformation algorithm applied to a programmable digital shaping filter (44), so as to digitally minimize distortion of the peak shape.

    Abstract: A filter circuit for a biaxial signal, etc. which has an excellent sharp filtering characteristic in a narrow band, without performing conversion/inverse conversion from a coordinate system at rest to a rotatory coordinate system. Input signals related to two axes orthogonal to each other are expressed by one complex variable ( u = Ux + jUy: where Ux and Uy are Laplace transformation values of the respective signals). A complex coefficient transfer function F (s - j omega ) which is obtained by replacing the Laplacian s of F(s) is used as the transfer function of real number coefficient of a low- or high-pass filter. Output signals related to two axes orthogonal to each other and passing the input complex variable u through a complex coefficient transfer function F (s - j omega ) are expressed by one complex variable ( V = Vx + jVy: where Vx and Vy are Laplace transformation values of the respective signals). The connection is made with transfer elements of real number coefficient so that the real part and the imaginary part of a transfer expression equation which is obtained by multiplying both sides of a transfer expression equation U . F (s - j omega ) = V of U , F and V as defined above by the denominator of F (s - omega ) may be equal to each other.

    Abstract: Impulse noise suppression upstream of digital processing circuitry contains a sample and hold (S/H) mechanism (24) which samples the input signal and stores a plurality of sequential samples representative of the amplitude of the input signal at successive times. The contents of the S/H are compared with an input signal sample (22) to determine whether there are abnormal amplitude variations which potentially constitute impulse noise. In one embodiment the comparison is referenced to the average magnitude (fig. 6) of the input signal. In another embodiment a cascaded arrangement (fig. 5) of S/H circuits (54-1-N) sample and store a plurality of sequential samples values. The contents of the last S/H circuit (54-N) are compared with the contents of each of selected other S/H circuits of the cascaded chain. A potential noise impulse sample is prevented from being coupled to downstream processing circuitry. Otherwise it is coupled through a downstream lowpass filter for subsequent signal analysis.

    Abstract: A push-pull tunable coupler includes a push transformer, a pull transformer and two compound Josephson junctions arranged in upper and lower branches. Absent biasing, the balanced push and pull of current between the branches causes current from a first object to circulate within a loop and not to be coupled to a second object. Biasing of at least one of the compound Josephson junctions unbalances the push and pull of current in the branches to couple the first and second objects. The coupler has reduced sensitivity to differential-mode noise around the off state, is completely insensitive to common-mode noise, and is capable of inverting the coupled signal with appropriate relative biasing of the compound Josephson junctions.

    Abstract: The de-Qing loss and phase imbalance caused by the inherent capacitance of a switched resistance, such as a MOSFET with a resistor, can be reduced by using a shunting switch across the resistor that is in series with the resistor's switch. The shunting switch shorts across the resistor when the resistor's switch is open and in reference mode, thereby significantly reducing the resistance in series with the inherent capacitance of the open resistor's switch.
